The 2010 24 Hours of Nürburgring was an endurance sports car race held at the Nürburgring Nordschleife race track in Germany on May 13–16. The event saw a return of most prominent entries, except the Ford GT, as team Raeder had discontinued this project. To give teams time to rest or for repairs before the race, the night practice was scheduled on Thursday evening. In cold and wet conditions, the Farnbacher-entered Ferrari F430 GTC set the best lap time before the session was red-flagged due to fog. In Friday afternoon qualifying, held in fair weather, it crashed out and was barely repaired in time for the race. Four of the five factory-backed Audi R8 LMS (officially entered by "customers", which happen to be the Audi-DTM-teams Phoenix Racing and Abt Sportsline) occupied the first four places on the grid, with Marco Werner setting pole at 8:24.753 with a new record average speed of . With lap times around 8:29, three of Porsche's new SP9/GT3-class cars occupied places 5 to 7, two of them entered by four-time winner Team Manthey, which had chosen to let the #1 car do only a single lap. BMW had entered two of their ALMS BMW M3 GT2, run by Schnitzer Motorsport. Due to the modifications that include a transaxle gear box, they do not comply to the standard rules set of SP classes and their "Balance of Performance". Along with a factory-entered Porsche GT3 Hybrid, the GT2-BMWs have thus been grouped into the E1-XP class for experimental factory entries. The better BMW and the Hybrid posted times of 8:32 and 8:34 in qualifying. Save for the 16th placed GT3-class Dodge Viper, only several other Porsche, Audi R8 and V8-powered BMW Z4 GT3 have qualified in the top 20, with times up to 8:47, which earns them a blue flash light that is supposed to facilitate passing of the approx. 180 slower cars. Porsche test driver Walter Röhrl had intended to enter on a standard road legal Porsche 911 GT3 RS, but had to withdraw due to health reasons from the team that comprises racers Roland Asch and Patrick Simon, plus journalists Horst von Saurma and Chris Harris. The car, entered in cooperation with sport auto (Germany), is registered as S-GO 2400, and was driven from Weissach to Nürburg. It has qualified with 9:15, 42nd overall, and 9th among the 17 SP7 class entrants, only beaten by
